Purpose: To evaluate ocular risk factors related to asymmetric visual field defects in normal tension glaucoma (NTG). Methods: We retrospectively evaluated 92 NTG patients (184 eyes) with asymmetric visual field defects; these patients were classified as having more affected eye (ME) group or less affected eye (LE) group. The differences between ME and LE based on the intra-individual comparison were assessed with several ocular risk factors such as best corrected visual acuity, refractive error, intraocular pressure (IOP), the number of glaucoma medications, disc hemorrhage, central corneal thickness, zone β of peripapillary atrophy (PPA), and disc size. All subjects were divided into two groups according to the severity of bilateral mean deviation (MD, Δ6dB) and evaluated. Results: The MD was -11.2±6.5 in the ME group, and -5.9±5.4 in the LE group (p=0.00). The optic disc size was 2.62±0.8 in the ME group, 2.48±0.5 in the LE group (p=0.00), and there were no statistically significant differences in the other factors. Regarding the difference in the MD, the optic disc size was statistically significant in the less different group, and the angle of PPA was statistically significant in the more different group (p=0.00 and p=0.01, respectively). Conclusions: The optic disc size is a risk factor related to visual field defects in the ME group and the less affected patients, and the PPA is a risk factor, thought to be associated with ischemia, related to visual field defects in the more affected patients with asymmetric normal tension glaucoma.

The research and development of curtain wall construction management are very insufficient due to economic difficulty and imbalance of manpower demand and supply of curtain wall construction enterprises. The theoretical consideration of construction productivity was carried out to suggest a necessity of construction prediction about working days in the domestic construction work, and the necessity of construction period calculation was suggested by understanding the actual condition of the curtain wall construction through characteristics of curtain wall and comparisonㆍanalysis of the present situation. After the working days' prediction method of the existing curtain wall construction was classified into regression analysis, factor analysis and hierarchical multiple regression analysis and considered to establish a prediction model to be suggested in the present study, a regression model process was established by selecting regression analysis as an analysis method using an objective quantified numerical value, and thus the working days' prediction model was built by setting an architectural area, working manpower, the number of total floors as an influence factor affecting major variables of working days' prediction of the curtain wall construction. It is expected that it will be helpful for a curtain wall construction builder to set up a proper construction period through the predicting regression mode in the construction planning stage.

Background & Purpose : This purpose of this study was to determine the prognostic factors for hepatocellular carcinoma (HCC) in patients who received curative hepatectomies at our institution. Patient and Method : A retrospective analysis was performed on 457 patients who had undergone hepatectomies between Mar 1987 and Feb 2008 for HCC at the Korea Cancer Center Hospital, Seoul, Korea. The number of males enrolled in the study was 366 and the numbr of fenales enrolled was 91. The mean age of the patients was 52.8 years old. Hepatitis B virus-related disease was the most frequent etiology (335/457 patients). Two hundred nine(209) patients had liver cirrhosis, and 93.9% of patients were classified in Child-Pugh Class A. Results : The complication rate was 30.6%(140/457) and the operative mortality was 1.5%(7/457). Reoperation was performed in 7 complicated patients. Five-and 10-year overall survival rates of the patients were 57.7% and 41.8% respectively. Poor prognostic factors of overall survival were Child B class, Edmonson-Steiner histologic grade 3 or 4, tumor vascular invasion, and postoperative complications. Five-and 10-year disease-free survival rates were 42.7% and 32.5%, respectively. Poor prognostic factors for disease free survival included the following an Edmonson-Steiner histologic grade of 3 or 4, tumor vascular invasion, and postoperative complications. Conclusion : Postoperative complication is independently a poor prognostic factor for overall and disease free survival in our study. We suggest that special care is needed while performing hepatic resections for the treatment of HCC in order to reduce postoperative complications.

Purpose: To evaluated the effect of cataract surgery on intraocular pressure (IOP) in primary angle-closure glaucoma (PACG) and primary open-angle glaucoma (POAG), and to find predictors for a favorable postoperative IOP after cataract surgery in patients with coexisting cataract and glaucoma. Methods: Various clinical factors were evaluated in 68 patients (76 eyes) with well controlled primary glaucoma who had undergone cataract surgery. The differences in parameters between groups divided by postoperative IOP course were analyzed. Results: For this study, successful IOP control was defined as an IOP between 6 mmHg and 21 mmHg without anti-glaucoma medication at last visit after cataract surgery. Eyes with the highest preoperative IOPs less than 28 mmHg in POAG and 42 mmHg in PACG had a significantly higher probability of success. In PACG, the probability of success was significantly higher, if fewer than three anti-glaucoma medications were given before surgery and if the areas of PAS before surgery were less than 4 hours. Conclusions: Primary small incision cataract surgery using phacoemulsification and foldable intraocular lens implantation could be considered the procedure of choice for a selective group of patients with coexisting glaucoma and visually significant cataract, with respect to IOP, the number of anti-glaucoma medications, and the area of peripheral anterior synechiae.

Purpose: To evaluate the factors associated with the success of Ahmed glaucoma valve implantation in refractory glaucoma. Methods: The medical records of 45 eyes of 45 patients that underwent Ahmed implant surgery for the treatment of refractory glaucoma were reviewed retrospectively. The success criterion was a stable postoperative intraocular pressure (IOP) between 6 and 21 mmHg with or without antiglaucoma medications during the study period. Failure was defined as an abnormal IOP outside of the above range on two consecutive visits, and cases that needed additional surgery to control IOP or to treat devastating surgical complications. We compared the differences in various clinical factors before surgery between the success and failure groups. Results: The Kaplan-Meier cumulative success rate was 71.1% at 12 months. Among the various clinical factors age, gender, right or left eye, phakia or pseudophakia, systemic disease such as diabetes and hypertension, preoperative IOP, preoperative number of antiglaucoma medications, and the number of previous glaucoma or other ocular surgeries were not significantly different between the success and failure groups. Implantation at the superotemporal site and steroid non-responsders of the fellow eye showed a significantly greater success rate than the superonasal site and steroid responders, respectively, after Ahmed glaucoma valve implantation. Conclusions: The efficacy of lowering the IOP of an Ahmed glaucoma valve would be expected to be greater if the patient is a steroid non-responder. Given the same conditions in the superotemporal and superonasal areas, implanting the Ahmed glaucoma valve in the superotemporal quadrant showed an ito increased success rate.

Purpose: To evaluate the usefulness of external bandage suture for bleb-related management that follows trabeculectomy with mitomycin C. Methods: External bandage sutures were performed on 10 patients having hypotony maculopathy, persistent low intraocular pressure (IOP) caused by either hyperfiltration or focal leakage, or a persisting large bleb caused by hyperfiltration and who received trabeculectomy using mitomycin C as an adjuvant treatment. The changes in IOP measured before and 4 weeks after the procedure along with complication incidences were evaluated. Results: The mean IOP 4 weeks after the procedure compared with the mean IOP prior to the procedure increased from 5.8 ± 2.0 mm Hg (3.0-9.0 mm Hg) to 14.1 ± 8.5 mm Hg (4.0-32.0 mm Hg), with statistical significance (p = 0.008). After the procedure, improvement in visual acuity was observed but without statistical significance. One patient had persistent focal leakage from an avascular bleb and conjunctival advancement with removal of the avascular conjunctiva was performed. Conclusions: An external bandage suture can be a good alternative for correction of post-trabeculectomy hypotony and severe chemosis with minimal effect on blebs while correcting focal leakage and hyperfiltration.

Purpose: To observe the effects of biodegradable collagen matrix (OculusGenTM) on filtering bleb formation and maintenance and to investigate its clinical effects and usefulness in trabeculectomy. Methods: Ophthalmologic examinations were preformed 1 day, 2 weeks, 1 month, 2 months, 3 months, 6 months, and 12 months postoperatively in the case and control groups. The clinical findings of the filtering bleb were observed, and the clinical effects measured by mean intraocular pressure and complications were evaluated in both groups. Results: The success rates were 76% in the case group and 88% in the control group, and there were no significant differences between the case and control groups. In the case group, postoperative conjunctival injection persisted for more than 1 month with increasing severity, while ultrasound biomicroscopy revealed increased echogenicity of the subconjuctival and tenon tissue with no definite space-occupying effect. Conclusions: Trabeculectomy utilizing collagen matrix showed similar clinical results compared to the current traditional trabeculectomy; slit-lamp and ultrasound biomicroscopy findings did not reveal any advantageous changes to filtering bleb function.
